De Liliifloris Notulae 9. The only hitherto known Spiloxene species (Hypoxidaceae) from Namibia is a new species, Spiloxene etesionamibensis, and a new Spiloxene species from Namaqualand (Northern Cape), S. namaquana (original) (raw)

The only Namibian species of Spiloxene is described and illustrated by drawings and photos as Spiloxene etesionamibensis U.MÜLL.-DOBLIES, MARK.ACKER-MANN, WEIGEND &. D.MÜLL.-DOBLIES. It was hitherto misinterpreted as Spiloxene scullyi (BAKER) GARSIDE in SÖLCH & ROESSLER (1969) in MERX-MÜLLER's Prodromus einer Flora von Südwestafrika, but its closest ally is S. flaccida (NEL) GARSIDE, found in the Western and the Eastern Cape. Spiloxene etesionamibensis, which was found independently by GIESS & MERXMÜLLER and by MÜLLER-DOBLIES, is only known from two or three independent collections from a single locality. S. scullyi is no longer known from Namibia. In addition to the eight Spiloxene species already known from the Northern Cape Spiloxene namaquana U.MÜLL.-DOBLIES, MARK.ACKERMANN, WEIGEND & D.MÜLL.-DOBLIES is described and illustrated by drawings and photos. Its closest ally is Spiloxene trifurcillata (NEL) FOURC. from the Eastern Cape. For Spiloxene namaquana the morphological analysis of the branching pattern of an annual shoot taken in 1988 in the field is evaluated by a longitudinal and a horizontal diagram with explanatory remarks. The unusual innovation system of extreme anisoiteration is discussed. On Map 1 the quarter degree squares of the type localities (± only known localities) of both species is given.
